Title: Improvements in or relating to power transmission systems for baling machines
IPC: A01F15/08
Filed: 1952-07-23
Abstract: 721,244. Baling-presses. JONES, D. T., and JONES, G. Aug. 6, 1953 [July 23, 1952], No. 18568/52. Class 94 (1). The power transmission system of a baling press comprises a longitudinal shaft 11 which is offset from the centre line of the baling chamber and carries at one end a pinion 25, meshing with a crown wheel 33 on a transverse crankshaft 32, 32a driving the ram, and at the other end a fly wheel pulley 12 disposed externally of the body 10 of the press and having mounted thereon means, e.g. a universal coupling 16, for connection to the power take-off of a tractor or other towing vehicle. The fly wheel 12 may thus be driven either through the coupling 16 or by means of a belt from a stationary source, of power. The fly wheel is a running fit on the shaft and is connected to a flanged member 17, keyed to the shaft, by a shear pin 20 or other overload release coupling. The crank arms 38 are coupled by a pin 40 to a connecting rod '41 which reciprocates the ram. A sprocket 48 on the shaft 32a drives the "pick-up" rotor and other working parts of the press, such as the bale-tying mechanism, are driven from a shaft 42 carrying a bevel gear 45 which meshes with a bevel gear 46 on the shaft 32a.

Title: Method of and means for sharpening saws
IPC: B23D63/12
Filed: 1921-07-09
Abstract: 187,004. Herbert, E. G. July 9, 1921. Saws, sharpening.-A hack-saw or other straight saw is sharpened by bringing it into meshing engagement with toothed guides and simultaneously into engagement with a grinding- wheel, the teeth on the guides serving to guide and limit the movement of the saw in relation to the grinding-wheel. The saw e, Fig. 7, is mounted on a table f which is s 1 i d a b I v mounted on a slotted table c and is moved by hand or by power to bring the saw into engagement with guides a, b and with the grinding- wheel m. The guides are fixed to the table c, or to two tables with a gap between them; the guides may comprise portions of a saw similar to that being sharpened, or may comprise milled strips. The table f is moved on the table c in a circular path by means of an eccentric h of adjustable eccentricity, the table f being maintained parallel to itself by means of spring- pressed triggers k carried by a shaft j and bearing against the table. The blade is held on the table by spring blades l<1> carried by a spring- pressed lever pivoted to the table and carrying also a stud l<2> which bears against the back of the saw. The pivotal movement of the lever l is limited by an adjustable stop l<3> which bears against the edge of the table. The grinding- wheel m is bevelled on its periphery and is adjustable towards and from the saw by a screw g, and parallel thereto by a screw r acting on the axle s of the wheel against the pressure of a spring t, a ball bearing u taking the thrust. In operation, the grinding-wheel is adjustable to project into the slot in the table c, and its bevelled periphery occupies the space of one of the teeth missing between the two guides a, b. The movement of the table f brings the blade. teeth against the guide-teeth, and, by the combined effect of the movement of the table, the slipping of the saw on the table, and the action of the lever e, the blade moves in the path shown in Fig. 5; thus all of the teeth are ground both on the back and on the front to the correct shape.

Title: Improvements in or relating to Semiconductor Voltage Reference Devices
IPC: H03G11/02
Filed: 1967-04-24
Abstract: 1,179,745. Semi-conductor devices SIEMENS A.G. 24 April, 1967 [25 April, 1966], No. 18706/67. Heading H1K. A voltage reference device comprises a plurality of Zener diodes, formed in a monolithic integrated circuit and isolated from one another by PN junctions and having a positive temperature coefficient of Zener voltage, connected in series with at least one of the diodes being poled in the forward direction relative to the others. Since the diodes are arranged to have a positive temperature coefficient in the reverse direction and have a negative temperature coefficient of voltage in the forward direction, the net temperature coefficient can be made small by connecting one or more forward biased diodes in series with the reverse biased diodes. As shown, Fig. 2, an N+ type epitaxial layer (2) is grown on a P-type silicon substrate (1), the surface is masked with silicon dioxide and a P+ type grid 3 is diffused completely through the epitaxial layer to divide it into a plurality of regions 2a. A P+ type region 4 is diffused into each of the regions. 2a to a depth insufficient to reach the P-type substrate 1 to form a plurality of identical Zener diodes. The characteristic of one of the diodes is measured and the number of diodes necessary to produce the required reference voltage are connected in series by vapour deposited or printed-on conductive strips 6 which extend over oxide layer 5. For example, the first six diodes in the series chain between terminals K and A4 form the voltage reference section of the device and temperature compensation is provided by including one, two or three forward biased diodes by making the anode connection terminal A2, A3 or A4. Leads may may be attached by thermocompression bonding. In a modification the starting wafer is of N+ type conductivity and the grid (3) is diffused completely through the wafer. In this case the P+ type regions (4) may also extend completely through the wafer. The conductivity types of the regions may be interchanged, silicon nitride may be used as a protective layer instead of silicon dioxide and output electrodes may be arranged at suitable points in the series chain to provide alternative stabilized voltage levels.

Pressure on a BELT key 226, Fig. 1, latches the idler mandrel 20 forward so that belt record 22 may be edged out of the machine 10 by applying a thumb-nail to the left-hand edge of the exposed portion. On inserting a belt, trigger means, encountered by the leading edge of the belt when pushed beyond its running position, trips the latch, the idler mandrel snaps back and the belt is tensioned in running position. The key 226, when pressed, rocks a lever 228 about 230, a disc 234 latching behind a trigger tab 244, the action also raising an arm 236, eccentrically pivoted at 240 to ease the belt tension against the action of spring 242. On loading, flange 258 limits the insertion of the rear end of the belt, but further movement of the front end of the belt results in contacting trigger pad 260, the consequent snap action of the idler mandrel 20 straightening the belt. A further linkage 256 with key 226, Fig. 5, raises recording and playback styli from the belt for unloading. If the machine is started without a belt loaded, the member 254, Fig. 5, moving with key 226 (which is necessarily latched down, in the absence of a loaded belt to trigger it) rocks an assembly 262, 266 so that the end of arm 266 is brought into contact with one of the drive gears 60 to give an audible warning rattle. Carriage back-spacing and auto-stop means, and an imminent end-of-record warning rattle means are also described.
